Abstract (en)

[origin: EP1394623A2] The image forming apparatus includes an image forming unit capable of forming an image with a hypochromic toner and a hyperchromic toner of a substantially same hue, a first toner containing portion containing the hypochromic toner, a second toner containing portion containing the hyperchromic toner, and a density detecting unit which detects a density of an image formed with the hypochromic toner and the hyperchromic toner. Thus an image can be formed with the hypochromic toner and the hyperchromic toner of a substantially same hue.
